There were two major brush fires in Redding over the weekend.  Redding Fire & EMS officials say these are very dangerous and resource-depleting operations.  DEEP and Aquarion Police are investigating the fire on the northeast shore of Saugatuk reservoir in the Greenbush Road area.  Neighboring fire departments answered the call for several additional medical and fire incidents while the blazes were being handled.  Residents are asked to be extra vigilant about discarding smoking materials. Outside burning of all sorts should be curtailed until conditions improve.  Redding Fire officials say last night's showers were not enough.
